The center will also ask for the process material to which the product was last exposed. Individuals who handle products exposed to a hazardous substance can avoid injury if they are informed of and understand the hazard. If the product being returned was exposed to a hazardous substance as defined by OSHA, a copy of the required Material Safety Data Sheet (MSDS) for each hazardous substance identified must be included with the returned goods. Rosemount National Response Center representatives will explain the additional information and procedures necessary to return goods exposed to hazardous substances. DEVICE DESCRIPTION NODE ADDRESS TAGGING Before configuring the device, ensure the host has the appropriate Device Description file revision for this device. The device descriptor can be found on The initial release of the Rosemount 3051S with FOUNDATION fieldbus protocol is device revision 20. This manual is for revision 23. The transmitter is shipped at a temporary (248) address. This will enable FOUNDATION fieldbus host systems to automatically recognize the device and move it to a permanent address. Commissioning Tag The 3051S has been supplied with a removable commissioning tag that contains both the Device ID (the unique code that identifies a particular device in the absence of a device tag) and a space to record the device tag (PD_TAG) (the operational identification for the device as defined by the Piping and Instrumentation Diagram (P&ID)). When commissioning more than one device on a fieldbus segment, it can be difficult to identify which device is at a particular location. The removable tag, provided with the transmitter, can aid in this process by linking the Device ID to its physical location. The installer should note the physical location of the transmitter on both the upper and lower location of the commissioning tag. The bottom portion should be torn off for each device on the segment and used for commissioning the segment in the control system. 1-2

12 Rosemount 3051S Reference Manual Analog Input Block The Analog Input (AI) Function Block processes the measurements from the sensor and makes them available to other function blocks. The output value from the AI block is in engineering units and contains a status indicating the quality of the measurement. The AI block is widely used for scaling functionality. Input Selector Block The Input Selector (ISEL) Function Block can be used to select the first good, Hot Backup, maximum, minimum, or average of as many as eight input values and place it at the output. The block supports signal status propagation. Integrator Block The Integrator (INT) Function Block integrates one or two variables over time. The block compares the integrated or accumulated value to pre-trip and trip limits and generates discrete output signals when the limits are reached. Arithmetic Block The Arithmetic (ARTH) Function Block provides the ability to configure a range extension function for a primary input. It can also be used to compute nine different arithmetic functions. Signal Characterizer Block The Signal Characterizer (SGCR) Function Block characterizes or approximates any function that defines an input/output relationship. The function is defined by configuring as many as twenty X,Y coordinates. The block interpolates an output value for a given input value using the curve defined by the configured coordinates. Two separate analog input signals can be processed simultaneously to give two corresponding separate output values using the same defined curve. PID Block The PID Function Block combines all of the necessary logic to perform proportional/integral/derivative (PID) control. The block supports mode control, signal scaling and limiting, feed forward control, override tracking, alarm limit detection, and signal status propagation. The block supports two forms of the PID equation: and Series. You can choose the appropriate equation using the MATHFORM parameter. The ISA PID equation is the default selection. Integrator Block The Integrator Block is used as a totalizer. This block will accept up to two inputs, has six options how to totalize the inputs, and two trip outputs. Control Selector Block The Control Selector Function Block selects one of two or three inputs to be the output. The inputs are normally connected to the outputs of PID or other function blocks. One of the inputs would be considered Normal and the other two overrides. 1-4

A Quick Installation Guide for this product (document number ) is shipped with every transmitter to describe basic installation, wiring, and startup procedures. Dimensional drawings for each Rosemount 3051S variation and mounting configuration are included in Appendix B: Specifications and Reference Data. Procedures and instructions in this section may require special precautions to ensure the safety of the personnel performing the operation. Information that raises potential safety issues is indicated with a warning symbol ( ). Refer to the following safety messages before performing an operation preceded by this symbol. Warnings Explosions can result in death or serious injury. Do not remove the transmitter covers in explosive environments when the circuit is live. Fully engage both transmitter covers to meet explosion-proof requirements. Before connecting a communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices. Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications.

16 Rosemount 3051S Series Reference Manual Electrical shock can result in death or serious injury. Avoid contact with the leads and terminals. Process leaks could result in death or serious injury. Install and tighten all four flange bolts before applying pressure. Do not attempt to loosen or remove flange bolts while the transmitter is in service. Replacement equipment or spare parts not approved by Rosemount Inc. for use as spare parts could reduce the pressure retaining capabilities of the transmitter and may render the instrument dangerous. Use only bolts supplied or sold by Rosemount Inc. as spare parts. Improper assembly of manifolds to traditional flange can damage SuperModule Platform. For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt hole) but must not contact module housing. Upper and lower unit labeling must match exactly to maintain hazardous location approvals. When upgrading, it is imperative that approval codes match between the SuperModule and the electronics housing. CONSIDERATIONS General Measurement performance depends upon proper installation of the transmitter and impulse piping. Mount the transmitter close to the process and use minimum piping to achieve best performance. Also, consider the need for easy access, personnel safety, practical field calibration, and a suitable transmitter environment. Install the transmitter to minimize vibration, shock, and temperature fluctuation. IMPORTANT Install the enclosed pipe plug (found in the box) in the unused conduit opening. For straight threads, a minimum of 6 threads must be engaged. For tapered threads, install the plug wrench-tight. For material compatibility considerations, see document number on Mechanical NOTE For steam service or for applications with process temperatures greater than the limits of the transmitter, do not blow down impulse piping through the transmitter. Flush lines with the blocking valves closed and refill lines with water before resuming measurement. NOTE When the transmitter is mounted on its side, position the Coplanar flange to ensure proper venting or draining. Mount the flange as shown in Figure 2-2 on page 2-9, keeping drain/vent connections on the bottom for gas service and on the top for liquid service. 2-2

17 Reference Manual Rosemount 3051S Series Draft Range Installation For the 3051S_CD0 draft range pressure transmitter, it is best to mount the transmitter with the isolators parallel to the ground. Installing the transmitter in this way reduces oil mounting effect and provides for optimal temperature performance. Be sure the transmitter is securely mounted. Tilting of the transmitter may cause a zero shift in the transmitter output. Reducing Process Noise There are two recommended methods of reducing process noise: output damping and, in gage applications, reference side filtering. Reference Side Filtering In gage applications it is important to minimize fluctuations in atmospheric pressure to which the low side isolator is exposed. One method of reducing fluctuations in atmospheric pressure is to attach a length of tubing to the reference side of the transmitter to act as a pressure buffer. Another method is to plumb the reference side to a chamber that has a small vent to atmosphere. If multiple draft transmitters are being used in an application, the reference side of each device can be plumbed to a chamber to achieve a common gage reference. Environmental Access requirements and cover installation on page 2-4 can help optimize transmitter performance. Mount the transmitter to minimize ambient temperature changes, vibration, mechanical shock, and to avoid external contact with corrosive materials. Appendix B: Specifications and Reference Data lists temperature operating limits. 2-3

18 Rosemount 3051S Series Reference Manual INSTALLATION PROCEDURES For dimensional drawing information refer to Appendix B: Specifications and Reference Data on page B-15. Process Flange Orientation Mount the process flanges with sufficient clearance for process connections. For safety reasons, place the drain/vent valves so the process fluid is directed away from possible human contact when the vents are used. In addition, consider the need for a testing or calibration input. Housing Rotation See Consider Housing Rotation on page Terminal Side of Electronics Housing Mount the transmitter so the terminal side is accessible. Clearance of 0.75 in. (19 mm) is required for cover removal. Use a conduit plug in the unused conduit opening. Circuit Side of Electronics Housing Provide 0.75 in. (19 mm) of clearance for units with out an LCD display. Three inches of clearance is required for cover removal if a meter is installed. Cover Installation Always ensure a proper seal by installing the electronics housing cover(s) so that metal contacts metal. Use Rosemount O-rings. Cover Jam Screw For transmitter housings shipped with a cover jam screw, as shown in Figure 2-1, the screw should be properly installed once the transmitter has been wired and powered up. The cover jam screw is intended to disallow the removal of the transmitter cover in flameproof environments without the use of tooling. Follow these steps to install the cover jam screw: 1. Verify that the cover jam screw is completely threaded into the housing. 2. Install the transmitter housing cover and verify that the cover is tight against the housing. 3. Using an M4 hex wrench, loosen the jam screw until it contacts the transmitter cover. 4. Turn the jam screw an additional 1/2 turn counterclockwise to secure the cover. (Note: Application of excessive torque may strip the threads.) 5. Verify that the cover cannot be removed. 2-4

22 Rosemount 3051S Series Reference Manual Impulse Piping The piping between the process and the transmitter must accurately transfer the pressure to obtain accurate measurements. There are five possible sources of error: pressure transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid in a gas line, density variations between the legs, and plugged impulse piping. The best location for the transmitter in relation to the process pipe depends on the process itself. Use the following guidelines to determine transmitter location and placement of impulse piping: Keep impulse piping as short as possible. For liquid service, slope the impulse piping at least 1 inch per foot (8 cm per m) upward from the transmitter toward the process connection. For gas service, slope the impulse piping at least 1 inch per foot (8 cm per m) downward from the transmitter toward the process connection. Avoid high points in liquid lines and low points in gas lines. Make sure both impulse legs are the same temperature. Use impulse piping large enough to avoid friction effects and blockage. Vent all gas from liquid piping legs. When using a sealing fluid, fill both piping legs to the same level. When purging, make the purge connection close to the process taps and purge through equal lengths of the same size pipe. Avoid purging through the transmitter. Keep corrosive or hot (above 250 F [121 C]) process material out of direct contact with the SuperModule and flanges. Prevent sediment deposits in the impulse piping. Keep the liquid head balanced on both legs of the impulse piping. Avoid conditions that might allow process fluid to freeze within the process flange.3 2-8

23 Reference Manual Rosemount 3051S Series Mounting Requirements Impulse piping configurations depend on specific measurement conditions. Refer to Figure 2-2 for examples of the following mounting configurations: Liquid Flow Measurement Place taps to the side of the line to prevent sediment deposits on the process isolators. Mount the transmitter beside or below the taps so gases vent into the process line. Mount drain/vent valve upward to allow gases to vent. Gas Flow Measurement Place taps in the top or side of the line. Mount the transmitter beside or above the taps so to drain liquid into the process line. Steam Flow Measurement Place taps to the side of the line. Mount the transmitter below the taps to ensure that impulse piping will remain filled with condensate. In steam service above 250 F (121 C), fill impulse lines with water to prevent steam from contacting the transmitter directly and to ensure accurate measurement start-up. NOTE For steam or other elevated temperature services, it is important that temperatures at the process connection do not exceed the transmitter s process temperature limits. See Process Temperature Limits on page B-11 for details. Figure 2-2. Coplanar Installation Examples GAS OR LIQUID SERVICE GAS SERVICE STEAM SERVICE FLOW 2-9

24 Rosemount 3051S Series Reference Manual Figure 2-3. In-Line Installation Examples GAS SERVICE GAS OR LIQUID SERVICE LIQUID OR STEAM SERVICE Process Connections 3051S transmitter flange process connection size is 1 /4 18 NPT. Flange adapters with 1 /2 14 NPT connections are available as the D2 option. Use your plant-approved lubricant or sealant when making the process connections. The process connections on the transmitter flange are on 2 1 /8-inch (54 mm) centers to allow direct mounting to a three-valve or five-valve manifold. Rotate one or both of the flange adapters to attain connection centers of 2 inches (51 mm), 2 1 /8 inches (54 mm), or 2 1 /4 inches (57 mm). Install and tighten all four flange bolts before applying pressure to avoid leakage. When properly installed, the flange bolts will protrude through the top of the SuperModule housing. Do not attempt to loosen or remove the flange bolts while the transmitter is in service. To install adapters to a Coplanar flange, perform the following procedure: 1. Remove the flange bolts. 2. Leaving the flange in place, move the adapters into position with the O-ring installed. 3. Clamp the adapters and the Coplanar flange to the transmitter module using the longer of the bolts supplied. 4. Tighten the bolts. Refer to Table 2-1 on page 2-6 for torque specifications. 2-10

25 Reference Manual Rosemount 3051S Series Failure to install proper flange adapter O-rings can cause process leaks, which can result in death or serious injury. The two flange adapters are distinguished by unique O-ring grooves. Only use the O-ring that is designed for its specific flange adapter, as shown below. ROSEMOUNT 3051S/ 3051/3001/3095/2024 Flange Adapter O-ring 3051S 3051C 2024 ROSEMOUNT 1151 PTFE Based Elastomer Flange Adapter O-ring PTFE Elastomer Refer to the Spare Parts list in Appendix B: Specifications and Reference Data for the correct part numbers of the flange adapters and O-rings designed for 3051S transmitters. Whenever you remove flanges or adapters, visually inspect the PTFE O-rings. Replace them if there are any signs of damage, such as nicks or cuts. If you replace the O-rings, re-torque the flange bolts after installation to compensate for cold flow. Refer to the process sensor body reassembly procedure in Section 5 Troubleshooting on page 5-6. Consider Housing Rotation The housing can be rotated to improve field access to wiring or to better view the optional LCD display. Perform the following procedure: Figure 2-4. Housings PlantWeb Housing Junction Box Housing Housing Rotation Set Screw (3/32-inch) 2-11

26 Rosemount 3051S Series Reference Manual 1. Loosen the housing rotation set screw. 2. First rotate the housing clockwise to the desired location. If the desired location cannot be achieved due to thread limit, rotate the housing counter clockwise to the desired location (up to 360 from thread limit). 3. Retighten the housing rotation set screw. In addition to housing rotation, the optional LCD display can be rotated in 90-degree increments by squeezing the two tabs, pulling out, rotating and snapping back into place. NOTE If LCD pins are inadvertently removed from the interface board, carefully re-insert the pins before snapping the LCD display back into place. Configure Security The 3051S FOUNDATION fieldbus transmitter has a hierarchy of security. The SECURITY switch located on the electronics provides the highest level of security. In the ON position, all writes to the transmitter are disabled. Simulate The SIMULATE switch is located on the Electronics. It is used in conjunction with the transmitter simulate software to simulate process variables and/or alerts and alarms. To simulate variables and/or alerts and alarms, the SIMULATE switch must be moved to the ENABLE position and the software enabled through the host. To disable simulation, the switch must be in the DISABLE position. 2-12

27 Reference Manual Rosemount 3051S Series NOTE It is important to know that Simulate is enabled only when the hardware senses the switch changing from DISABLE to ENABLE. If the power is removed with the switch in ENABLE, Simulate is not enabled. You must move the switch from ENABLE to DISABLE and then back to ENABLE to be able to use the Simulate software. WIRING Transmitter Wiring Wiring and power supply requirements can be dependent upon the approval certification. As with all FOUNDATION fieldbus requirements, a conditioned power supply and terminating resistors are required for proper operation. The standard 3051S pressure transmitter terminal block is pictured below. The terminals are not polarity sensitive. The transmitter requires 9-32 Vdc to operate. Type A FOUNDATION fieldbus wiring 18 awg twisted shielded pair is recommended. NOTE Avoid running instrument cable next to power cables in cable trays or near heavy electrical equipment. It is important that the instrument cable shield be: - trimmed close and insulated from touching the transmitter housing - continuously connected throughout the segment - connected to a good earth ground at the power supply end Figure 2-5. Minimize Distance Trim shield and insulate Ground for Transient Protection DP Connect Shield Back to the Power Supply Ground Insulate Shield FIELDBUS WIRING 2-13

28 Rosemount 3051S Series Reference Manual Transmitter Grounding Always ground the transmitter case in accordance with national and local electrical codes. A ground can be connected to the 3051S Transmitter either by an external ground lug or the internal ground lug. Both options can be seen in Figure 2-6. Figure S Inline SuperModule External Ground Connection 3051S Inline SuperModule External Ground Connection 3051S Internal Ground Connection The most effective transmitter case grounding method is a direct connection to earth ground with minimal (< 1 ) impedance. NOTE Grounding the transmitter case using the threaded conduit connection may not provide a sufficient ground. The transient protection terminal block (Option Code T1) will not provide transient protection unless the transmitter case is properly grounded. Use the above guidelines to ground the transmitter case. Do not run transient protection ground wire with signal wiring; the ground wire may carry excessive current if a lightning strike occurs. ROTATING THE LCD DISPLAY Transmitters ordered with the LCD display will be shipped with the display installed. The display can be rotated in 90 degree increments. To rotate the display: 1. Ensure the power is removed from the transmitter. 2. Remove the cover to expose the LCD Display. 3. Squeeze the two tabs that hold the meter in and gently pull. 4. Ensure the four-pin connector is still in the transmitter circuit board. If the connector stayed in the meter, remove it from the meter and insert it into the transmitter circuit board. 5. Get the LCD in the orientation desired, squeeze the two tabs to remove the meter and gently insert the meter in to the electronics circuit board. If the meter does not insert correctly, check the alignment of the four-pin connector and try again. 6. Install the meter cover and tighten to ensure metal-to-metal contact. 2-14

29 Reference Manual Rosemount 3051S Series Figure 2-7. Optional LCD Display LCD Display Meter Cover Setting Units ZEROING TRANSMITTER Damping Units for both the Sensor Transducer Block and the AI Block are set in the AI Block. To change units: Set the AI Block to OOS mode Select XD_Scale.units_index Select only one of the engineering units listed on page 3-10 Return AI Block to Auto mode Before operating the transmitter, perform a Zero Trim and set the Damping. Refer to page 4-4 for zeroing procedures. The damping parameter in the Transducer Block may be used to filter measurement noise. By increasing the damping time, the transmitter will have a slower response time, but will decrease the amount of process noise that is translated to the Transducer Block Primary Value. Because both the LCD and AI Block get input from the Transducer Block, adjusting the damping parameter will effect both blocks. NOTE The AI Block has it's own filtering parameter called PV_FTIME. For simplicity, it is better to do filtering in the Transducer Block as damping will be applied to primary value on every sensor update. If filtering is done in AI block, damping will be applied to output every macrocycle. ROSEMOUNT 305, 306 AND 304 MANIFOLDS The Rosemount 305 is available in two designs: Traditional and Coplanar. The traditional 305 Integral Manifold can be mounted to most primary elements with mounting adapters in the market today. The Rosemount 306 In-Line Manifold is used with In-line transmitters to provide block-and-bleed valve capabilities of up to psi (690 bar). The Rosemount 304 comes in two basic styles: traditional (flange x flange and flange x pipe) and wafer. The 304 traditional manifold comes in 2, 3, and 5-valve configurations. The 304 wafer manifold comes in 3 and 5 valve configurations. 2-15

30 Rosemount 3051S Series Reference Manual Figure 2-8. Integral Manifold Designs CONVENTIONAL COPLANAR TRADITIONAL IN-LINE Rosemount 305 Integral Manifold Installation Procedure To install a 305 Integral Manifold to a 3051S transmitter: 1. Inspect the PTFE SuperModule O-rings. If the O-rings are undamaged, reusing them is recommended. If the O-rings are damaged (if they have nicks or cuts, for example), replace them with new O-rings. IMPORTANT If replacing the O-rings, be careful not to scratch or deface the O-ring grooves or the surface of the isolating diaphragm when removing the damaged O-rings. 2. Install the Integral Manifold on the SuperModule. Use the four manifold bolts for alignment. Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern to final torque value. See Flange Bolts on page 2-5 for complete bolt installation information and torque values. When fully tightened, the bolts should extend through the top of the module housing. 3. If the PTFE SuperModule O-rings have been replaced, the flange bolts should be re-tightened after installation to compensate for cold flow of the O-rings. 4. If applicable, install flange adapters on the process end of the manifold using the 1.75-in. flange bolts supplied with the transmitter. NOTE Always perform a zero trim on the transmitter/manifold assembly after installation to eliminate mounting effects. See Section 4 Operation and Maintenance, Sensor Calibration, Zero Trim Method on page 4-4. Rosemount 306 In-Line Manifold Installation Procedure The 306 Manifold is for use only with a 3051S In-line transmitter. Assemble the 306 Manifold to the 3051S In-line transmitter with a thread sealant. 1. Place transmitter into holding fixture. 2. Apply appropriate thread paste or tape to threaded instrument end of the manifold. 3. Count total threads on the manifold before starting assembly. 4. Start turning the manifold by hand into the process connection on the transmitter. 2-16

31 Reference Manual Rosemount 3051S Series NOTE If using thread tape, be sure the thread tape does not strip when the manifold assembly is started. 5. Wrench tighten manifold into process connection. (Note: Minimum torque value is 425 in-lbs) 6. Count how many threads are still showing. (Note: Minimum engagement is 3 revolutions) 7. Subtract the number of threads showing (after tightening) from the total threads to calculate the revolutions engaged. Further tighten until a minimum of 3 rotations is achieved. 8. For block and bleed manifold, verify the bleed screw is installed and tightened. For two-valve manifold, verify the vent plug is installed and tightened. 9. Leak-check assembly to maximum pressure range of transmitter. Rosemount 304 Conventional Manifold Installation Procedure To install a 304 Conventional Manifold to a 3051S transmitter: 1. Align the Conventional Manifold with the transmitter flange. Use the four manifold bolts for alignment. 2. Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern to final torque value. See Flange Bolts on page 2-5 for complete bolt installation information and torque values. When fully tightened, the bolts should extend through the top of the module housing plane of flange web (i.e. bolt hole) but must not contact module housing. 3. If applicable, install flange adapters on the process end of the manifold using the 1.75-in. flange bolts supplied with the transmitter. 2-17
